Witnesses have identified the suspect as Donyelle Sims, 36, who has no known address. Sims has a criminal history and active warrants for her arrest, including aggravated battery, robbery with a deadly weapon and aggravated abuse of a disabled person.

On Feb. 23, at about 5:30 p.m. in the 2400 block of Pershing Avenue, the three bystanders — Cheryl Priester, Tonia Priester, and Patricia Robinson — heard a woman screaming. Sims was reportedly beating the victim with a large stick.

One of the bystanders called 911 for help as the three women ran to help the victim, who was screaming for Sims to stop. Sims allegedly stopped assaulting the victim, dropped the stick and fled, taking the victim's cellphone and bag of personal items. The victim, who suffers from a mental disability, sustained minor injuries to her arms, neck, shoulder and face.
